FOUNDER & LEAD DEVELOPER

I'm a project manager and full-stack developer with over 15 years of experience in the Shipping & Logistics industry. I've designed and shipped enterprise integrations for some of the world's largest carrier networks.

This API Trainer was built to help developers master the quirks of carrier integrations — from modern REST webhooks to legacy SOAP envelopes — based on real-world production incidents.
